GENERAL OVERVIEW  
The AD5246 provides a compact 2 mm × 2.1 mm packaged  
solution for 128-position adjustment applications. This device  
performs the same electronic adjustment function as a variable  
resistor. Available in four different end-to-end resistance values  
(5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ), these low temperature coefficient  
devices are ideal for high accuracy and stability variable  
resistance adjustments.  
The wiper settings are controllable through the I2C compatible  
digital interface, which can also be used to read back the present  
wiper register control word. The resistance between the wiper  
and either end point of the fixed resistor varies linearly with  
respect to the digital code transferred into the RDAC1 latch.  
Operating from a 2.7 V to 5.5 V power supply and consuming  
0.9 µA (3.3 V) allows for usage in portable battery-operated  
applications.
